Deep, deep, deep in the forest there is a long road going straight through it to connect one end with the other. One day 2 cars collide and are no longer able to drive. The group of people being in these vehicles have no other choice than to go and search for something... help, an exit, whatever, because none of them has a mobile to get help.
Unfortunately the forest is habitated by some dark creatures who like to eat human flesh... But that's not all. Those beings have way bigger plans, and so Alex and his new friends who drove the other car are now in a situation that is even supposed to destroy the earth!
